Heh I posted this thread b/c my car (2002 camry le) was in the shop after I hit a wolf/dog/coyote thing on the highway. Now I think the engine is toast because some dude didn't tighten my oil cap after my oil change. Indicator goes on when I'm in the left lane, engine is off by the time I hit the right lane and I end up coasting a quarter mile to get to the end of the off-ramp. I might be looking into this stuff in the very near future now- depends on what the word is on my car...
